Mark was near the front door when she was shot in the upper chest. Angerhofer was in the kitchen when she was fatally shot in the lower face, the Star Tribune reported.

“(Vessel) apparently went into their apartment, shot them both with the same .40-caliber gun,” Hennepin County Attorney Mike Freeman said at an afternoon news conference, the Star Tribune reported.

Police arrived around 10:30 p.m. and questioned Vessel, who claimed he did not hear anything, the Star Tribune reported.

Investigators found a blood-like substance on the wall of Vessel’s apartment and a .40-caliber gun, ammunition and a pill bottle with Vessel’s name on it in a trash bag thrown in the apartment complex trash bin.

Investigators learned Vessel had previously threatened to kill a neighbor and had shown a handgun to another tenant, WCCO reported.
